Specification of Letters Patent.

Patented June 26, 1917.

AppIication filed July 13, 1915.. Serial No. 39,708.

To all whom it may concern:

Be it known that I, PHILIP MALCAMP, a French subject, but who has applied for naturalization 0f the United States, and a resident of New Orleans, in the parish of Orleans and State of Louisiana, have invented a new and useful Improvement in Sterilizers, of which the following is a specification.

My invention is an improvement in sterilizers, and the invention has for its object to provide a sterilizer comprising a container for the material to be sterilized and having a cover supported by the container just above the level of the material and adapted to be agitated'by the boiling of the material and adapted for use with the wick heater forming the subject-matter of my c0- pending application, Serial No. 87 6,829, filed Dec. 12, 1914, wherein a damper is provided movable toward and from the wick to extinguish the same, and mechanism in the form of a swinging lever for lifting the damper when the outer end of the lever is depressed, and a lever balanced on the container and having at one end a depending rod adjustable with respect to the lever and engaging the first-named lever to hold the damper open, said first-named lever having a weight at the opposite end from the rod for normally moving the rod upward, and wherein a weight is provided resting loosely on the last-named lever and adapted to be dislodged by the movement of the cover for permitting the first-named weight to lift the rod to permit the damper to extinguish the flame.

In the drawings Figure 1 is a vertical section through the sterilizer and heater,

Fig. 2 is a partial sectional view similar to Fig. 1 with the parts in another position,

Fig. 3 is a top plan view of the sterilizer, and

Fig. 4 is a section on the line 4t4t of Fig. 2, looking in the direction of the arrows adj acent to the line.

In the present embodiment of the invention, the heater comprises an oil reservoir or tank 1, having a central double wall wick tube, consisting of 'an inner wall 2 and an outer wall 3, spaced apart from each other and connected at their bottom by a web 4. The wick 5 is mounted between the tubes 2 and 3 and the annular space between the tubular walls of the wicktube is connected to the reservoir by an inclined connecting pipe 6, leading from the bottom of the reservoir and opening into the bottom of the annular chamber of the wick tube.

The wick is raised and lowered by means of a hand wheel 7, secured to a shaft which is journaled in a sleeve 8, and the sleeve is supported at its outer end in a bearing bracket 9 on the reservoir. The shaft is connected with the wick to raise and lower the same when the shaft is oscillated in opposite directions in the usual manner. 7

An indicator 10 is secured to the shaft, and an arm 11 is secured to the sleeve, the arrangement being such that when the indicator and the arm are in register the wick will be at the proper position to obtain the best results. A damper 12, in the form of a disk, is secured to the upper end of a rod or shaft 13, the said rod or shaft being arranged at the axis of the wick tube and mounted to slide in a bearing sleeve 14, which is connected to the inner wall 2 of the wick tube, by arm 15.

A circular rib or web 16 depends from the damper 12 at the under side thereof, and a cylindrical screen 17 is supported by the rib. The lower end of the screen is connected to a ring 18, which fits within the wick, and the ring is connected to the shaft by means of a hub 19 and arms 20, the hub encircling the shaft or rod, and the arms connecting the hub to the ring.

The damper has a central opening through which the rod passes, and nuts 21 are threaded on to the rod on opposite sides of the damper. The damper is of a diameter to extend beyond the outer surface of the outer wall 3 of the wick tube, so that when the damper is in the lowest position of Fig. 2, it will close the upper end of the annular chamber of the wick tube.

The lower end of the rod or shaft 13 rests upon the flattened portion of a lever 22, which is pivoted as indicated at 23 intermediate the ends of the lever to a bracket 24, which depends from the supporting ring 25 of the reservoir. A weight 26 is slidably mounted on the outer end of the lever, and a set screw 27 is threaded through an arm 28, extending laterally outward from the bracket 24 above the lever. By means of the set screw the position of the damper 12 may be adjusted.

A chimney 29 of metal or the like is sup ported by a holder 30, concentric with the wick tube, and the ends of the chimney are open as shown, the upper end being reduced. At its lower end the chimney rests in the holder 30, and a perforate hood 31 is arranged between the top of the tank or reserv iiand the outer surface of the wick tube, the holder 31 being connected to this hood. The perforations of the hood permit the free entrance of air to theflame. The chimney is of metal shown, and the door is provided with panes of transparent inaterial, as for instance, isinglass or mica.

, The heater is supported the ring 25 before mentioned, and the said ring is connec'ted to standards or uprights 33, each standard or upright having a lateral lug 3% at each end, the. lugs at the lower ends of the uprights resting upon the supporting sarhce for the heater, while the lugs at 1e ether e'iid support a grid 35, having a cell al opening encircled a depending marginal rib 36. The grid has the usual depending flange at its outer end, and the container '37 for the material to be sterilized is supported by the grid over the central opening. V This receptacle is cylindrical in form, having an open top and near the rep the receptacle is provided with an inwardly en te'nding a'nnular rib '38. The cover 89 for the receptacle rests upon this rib, the said cover being a disk having a bail or handle 40, pivoted thereto for convenience in manipulating the cover. A

The r'b 38 is spaced below the top of the receptacle, and a lever 41 is supported by the receptacle above the cover. This lever is of a length to extend from one edge of the, grid to and beyond the other diametifically of the heater and the receptacle 37,

' and the rod ,is pivoted tothe cover at the edge remote from the weight 36 as indicated at 42, resting upon the cover at the opposite edge as skews.

A weight is is mounted to slide on the fed at the end ad'j'acent tothe pivotal connec- .t ioh, a'nd the lever is provided, with a stop 4;; at the said end, the stop being in the form of a ring ,passlng through an openin the a ar. as upsaacuag an is is provided passing through an opening 46 in the lever and is engaged a ,iiu't 4.7 above the lever. The lower end of the rod has a head as shown, which rests iipon the c'over at the edge remote from the pivotal eonnection of the lever.

An arm 48 extends radially outward from the receptacle 37 above the cover, and at. its

outer end thearni has spaeed upstanding arms 48 which extend on opposite sides of the lever. A threaded rod '60 is passed through threaded; opening in the lever outside of the arins 4L8, thesaid rod having a milled head 61 at its upper end for convenience in turning the same, and the lower end of the rod is provided with a hook 49 in the present instance,

sists of an upper section 51 and a lower section 52,- the meeting ends of the sections being threaded and being engaged by an internally threaded sleeve 53. From Fig. 1 it will be seen that the sections of the rod are threaded in opposite directions, and the sleet has an annular rib 54 atits center, the periphery of the rib bei-ii'g inilled or roughenefd as shown".

The uppr end efthe section 51 is provided i'vith a ring 55, which engages the liooli 49 of the rod 47. A weight 56 normanrests in a depression or recess '57 in the upper face of the lever just at the edge eras eassess adjacent a the an 45;, and this weight seen-nested to the radial arm l8 by means of a fleXible iiieinber 58, a chain one end of the connected to the weight and the other end to the radial arm.

The eentainef 3 155 at any desired ca- 'pac'it'y, and is arrangedto hold, the required afiwrea of material to b'e 'sterilized, as for instance, aquai t, with a little space between the serrate of the material amrthe devel- 39. The, material Should not fill the re cept'a'cle higher thanthe under surface of the rib 38 upon which the cover rests.

vThe pivotal connection of the, lever 41 with the receptacle is such. that it may be easily detached. AS shown this connection is made a -U'-shaped member, comprising a b'odjgwhi'ch is secured to the under Sui face ofthe lever, and arins depending from V the body, andeach arm is notched to receive the edgeo'f the receptacle. This provides for ard kiaginovement of the lever. on the receptaclefl'vith'out any longitudinal moveiiint of the lever and without anylateral swinging movement, while atthe same time the lever be easily detached merely by lifting it away from the receptacle.-

The rod 5 1-52-53 is ihade sectional to permit the use of containers 37of larger capacity. ,By turning the sleeve 53 in the proper direction the sections of the rod may be movedawa from or toward each other. A small pla e 59 is arranged at one side of the lever, in such manner that they ball weight 56 must fall always from the lever at the side thereof and can not fall from the other. side. It will be noted froman inspection of Fig. 4 that the bracket 24 which supports the lever,22 and the set screw 27 and in the lever, and the rod is engaged by nuts 64 at the outer side of the lugs 63.

A weight 65 is arranged on the cover near one edge and the cover is so placed with respect to the lever 41 that the weight will be at a point diametrically opposite the rod 4-5.

It is essential that the milk or other ma terial to be sterilized fill the vessel to near the cover 39 so that when the milk begins to boil the ebullition of the milk will lift the cover as indicated in Fig. 2. In sterilizing milk, the sterilization is complete as soon as the milk commences to boil and the process should then be stopped.

In operation the parts are arranged as shown in Fig. 1. The set screw 27 is turned up to a position such that when the lever 22 is free to move under the influence of gravity the damper 12 will drop down upon the end of the wick extinguishing the flame. The vessel containing the material to be sterilized is placed on the grid and the lever and connected parts are arranged as shown in Fig. l.

The sectional rod 51-52 is adjusted by means of the threaded rib until the damper is in the proper position to permit the wick to burn, that is, in somewhat the position of Fig. 1. The device is now ready for operation. As soon as the milk begins, to be disturbed by the boiling that edge of the cover remote from the weight will be lifted, lifting the rod 45.

It will be noted from an inspection of Fig. 1 that the edge of the nut 17 extends beneath the ball weight 56 in the recess 5'? far enough to dislodge the ball when the nut is lifted by the lifting of the rod. The weights of the several elements, namely, the

. damper 12 and its connections, the lever 22,

the weight 26, the sectional rod and sleeve and connections are so proportioned that when the ball weight 56 is in place the damper will be held lifted, and as soon as this weight is dislodged from the lever by the boiling movement of the milk, the weight of the damper and connected parts will swing the outer end of the lever 22 upward as shown in Fig. 2.

The damper dropping upon the burning wick will extinguish the Game, thus putting a stop to the further heating of the milk or other material being sterilized. The sterilizing attachment comprising the container 37, the cover, the lever 41 and connected parts are detachable from the heater merely by lifting them away. The ring 1 1 permits the lever ll and connected parts to be hung up out of the way, and when the container and other elements are removed the heater may be used for other purposes. The arms 418 of the radial arm 4-8 prevent or limit lateral swinging movement'of the adjacent end of the lever.

It will be noted from an inspection of Fig. 1 that the inner wall of the wick tube is of lesser height than the outer wall, and the damper 12 is shaped to lit against the upper ends of the walls, that is, the margin of the damper is offset upwardly with respect to the body of the damper, so that when the damper is in lowered position the margin will rest upon the upper end of the outer wall of the wick tube while the edge of the body of the damper will rest upon the upper end of the inner wall of the wick tube with the web which connects the offset margin with the body extending between the walls of the wick tube.

The upper end of the wick is preferal'ily beveled as shown, the arrangement being such that when the damper is in lowermost position, the air will be shut off entirely from the wick to immediately extinguish the flame. The ring 18 and the hub 19 guide the damper and'the rod, so that there will be no jamming of the damper to prevent its immediate fall when the weight 56 is dislodged.

The wick tube 23 is held in the central opening of the tank or reservoir by means of an angle ring 1. It will be noticed that the opening for the wick tube is of greater diameter than the external diameter of the tube itself, so that a space is left between the periphery of the tube and the reservoir. This angle ring 1" is provided with openings for permitting the air to pass upward in this space.
